Working notes A sulfur glass. May have dark interface reaction with copper-bearing (001116, 001408, 001417, 000116, 000144, 000145) and lead-bearing (001311, 001215, 000301, 000305) glasses. Learn more about possible reactions by reading our Reactive Potential of Bullseye Glass chart.
Reactions This is a reactive glass. It contains Sulfur (S) / Selenium (Se) and may react where it meets Copper (Cu), Lead (Pb), and Silver (Ag), forming a visible line or halo at the boundary. Use that on purpose to outline and add depth, or keep reactive colors apart to avoid it.
Using the ribbon Ribbon is a flat, wide strip of glass, heavier than a stringer, for bolder lines and woven or basket-style layouts. It fuses smoothly into the surface and holds a clean edge.
Fusing and compatibility Tested compatible with other Bullseye glass. When you combine it with glass from other makers, matching COE alone does not guarantee compatibility, so fire a small test tile first.
